Hygiene monitoring is critical when it comes to HACCP compliance. It is common for industries like prepared and processed foods, beverage and dairy to enroll in a HACCP program. Without proper hygiene monitoring by using atp testing kits or other means, there could be many quality issues.
A manufacturing company in any of the aforementioned industries might not only lose its image but end up with a huge loss if there was ever a product recall. With effective hygiene monitoring during food or beverage production, right from the beginning of the process till the end, there is hardly any possibility of product contamination. One of the best methods for contamination testing right now is ATP testing. This method of testing is so simple that anyone, even a person without any scientific background can carry out the test.
In addition, the test results are almost immediate, with some brands of luminometers giving the results in less than 15 seconds without any effect on accuracy at all. ATP or adenosine triphosphate is evident in all living animals and plants including microorganisms like bacteria, mold and yeast. It is actually a molecule which resides within the cell of a living being. So the presence of ATP in water, blood, food or such samples prove the existence of some kind of microorganism in the sample. In other words, there is some level of contamination.
When it comes to an atp testing kit, it normally comprises of cotton swabs and a handheld or portable luminometer. To begin with, the tester should wear a pair of suitable gloves. The type of gloves depends on where he is working. Then he uses a cotton swab to swab the necessary sample, food, water or anything else. The cotton swab is then put into a removable chamber, which is later inserted back into the handheld luminometer.
The reading on the device is usually in RLU or Relative Light Units. Since ATP transfers chemical energy within the cell, the concept of quantified energy presence is used. The reagent in the chamber has an enzyme called luciferase, which reacts with ATP. The ATP energy is then quantified in the form of light and measured in RLU. A higher RLU reading is an indication of more ATP presence, which means a higher level of contamination.
Currently, there are various brands of atp testing kits on the market. They vary in prices but generally, such a kit costs around $1500 on the market. Compared to sending samples for testing somewhere or establishing an internal laboratory to check on product contamination, buying this kind of kit is definitely more cost effective. Moreover, a great deal of time and energy can be saved. The test results are almost immediate and accurate.
Any layman can use this device, even the cleaner. Testing the contamination level of production, testing or surgical equipment surfaces after cleaning is a smart move to reduce the possibility of contamination. If the contamination level is high, then another cleaning can be done. So atp testing kits are useful not only for monitoring contamination of products during manufacturing but also for cleaning purposes at hospitals and such.
